Purification: This product was Protein A purified from monospecific antiserum.

Sterility: Sterile filtered

Immunogen:

Immunogen: This Protein A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to residues surrounding Y701 in the mouse STAT1 protein.

Immunogen Type: Conjugated Peptide

Isotype: IgG

Application Details

Application Notes:

Application Note: This affinity purified antibody has been tested for use in ELISA and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 91 kDa in size corresponding to phosphorylated Stat1 protein by western blotting in the appropriate cell lysate or extract.  This phospho-specific polyclonal antibody reacts with mouse Stat1 pY701 and shows minimal reactivity by ELISA against the non-phosphorylated form of the immunizing peptide.

Target Details for STAT1

Target: STAT1 (Signal Transducer and Activator of Transcription 1, 91kDa (STAT1))

Alternative Name: Stat1 (STAT1 Products)

Background: Background: This antibody is designed, produced, and validated as part of a collaboration with the National Cancer Institute (NCI). Signal transducer and activator of transcription 1 (Stat1) belongs to a family of cytoplasmic transcription factors that can be activated (phosphorylated) by cell surface receptors IFN (interferon), cytokine KITLG/SCF and other cytokines and other growth factors. Phosphorylation of Stat1 at Tyr701 induces Stat1 dimerization, nuclear translocation and DNA binding. Following type I IFN (IFN-alpha and IFN-beta) binding to cell surface receptors, signaling via protein kinases leads to activation of Jak kinases (TYK2 and JAK1) and to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize and associate with ISGF3G/IRF-9 to form a complex termed ISGF3 transcription factor, that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of IFN-stimulated genes (ISG), which drive the cell in an antiviral state. In response to type II IFN (IFN-gamma), STAT1 is tyrosine- and serine-phosphorylated. It then forms a homodimer termed IFN-gamma-activated factor (GAF), migrates into the nucleus and binds to the IFN gamma activated sequence (GAS) to drive the expression of the target genes, inducing a cellular antiviral state. Anti-Stat1pY701 Antibody is useful for researchers interested in transcription factor, cytokines and growth factor, Interleukin, Interferon gamma signaling, Cancer, Immunology, and Nuclear Signaling research.
